He said the new 1.4-L turbo four-cylinder, fully dressed, is 44 lb (20 kg) lighter than its counterpart in the current Chevrolet Cruze, and 8 lb (3.6 kg) lighter than VW's EA211-based 1.4 turbo. Mass reduction was a major design goal, according to Sutter. SAE-rated horsepower and torque will range from 75 to 165 hp (56 to 123 kW) and 70 to 184 lb Displacements are established by number of cylinders and six available crankshafts offering a selection of three different strokes-77.4, 81.3, and 86.6 mm (3.05, 3.20, and 3.41 in).ĭepending on market and vehicle application, the engines will use port fuel injection (naturally aspirated) or direct injection with turbocharging, and they will be calibrated for gasoline, E100, CNG, or bi-fuel LPG, according to Steve Keifer, Vice President of Global Powertrain Engineering.Īll were developed to achieve class-leading NVH, fuel efficiency, mass per displacement, and specific hp and torque ratings, as benchmarked against what Global Chief Engineer Tom Sutter considers to be the core competitive set: Volkswagen’s new EA211 family and Ford’s global Ecoboost engines of similar displacement. The 11 variants, all configured for 12 V stop-start, share a 74-mm (2.91-in) cylinder bore and 81-mm (3.19 in) bore centers. The new Ecotec range replaces three incumbent engine families. GM Powertrain engineers have revealed technical and development details of their company's all-new Modular Ecotec family of long-stroke 1.0- to 1.5-L three- and four-cylinder gasoline engines that the company expects will eventually power about 25% of the automaker’s global vehicle production in the A through C/D segments.
